These risks are classed as significant. They may have a high or low likelihood of occurrence, but their potential consequences are sufficiently serious to warrant appropriate consideration after those risks classed as ‘very high’. Consideration should be given to the development of strategies to reduce or eliminate the risks, but also mitigation in the form of at least multi-agency generic planning, exercising and training should be put in place and the risk monitored on a regular basis.
